GPM Racing #45 Steel Motor Gear 26T (48 Pitch,module: 0.5mm,motor Tooth Diameter: 5mm) (MG526T/0.5M)

Motor pinion for 48 pitch systems

This MG526T/0.5M motor pinion is a 26-tooth component made from 45 steel, sized for 48 pitch and module 0.5mm. The 5mm motor tooth diameter is compatible with many compact hobby electric motors used in a variety of RC vehicles.

It is commonly used to change final drive ratio or to replace a worn pinion without swapping the motor. Ensure both pitch and module match the mating spur gear before fitting to avoid inconsistent meshing.

Fitment tips: check axial alignment, set a small amount of backlash to avoid binding, and confirm the retention method on your motor fits a 5mm tooth diameter. Tighten fastenings to the recommended torque values for your motor mount hardware.

Tuning effect: using this 26T pinion increases theoretical top speed versus smaller pinions while reducing initial acceleration. Make adjustments in small steps and validate performance with test runs to find the optimal gearing for your setup.

Which motor shafts match this pinion?

This pinion is intended for motors that use a 5mm tooth diameter interface; measure the shaft and check the retention system before installing.

Are there maintenance steps to prolong pinion life?

Regular inspection, correct mesh setting, and keeping the gears clean and lightly lubricated will extend the life of a 45 steel pinion under hobby use.

Should I change other drivetrain components when swapping pinions?

Not necessarily, but verify the spur gear pitch and condition. If the spur shows wear or if the pitch/module do not match, consider replacing or correcting those components when changing pinions. Write Product Review Please sign in your account before you can write any review. Sign In Close
